anywAiR Ducted Zone Motors
24 V AC supply, RJ12 pinout and replacement motor harness compatibility
For zone motors used with anywAiR ducted zoning systems and compatible Advantage Air technology
Quick answer: The zone motors used with the anywAiR ducted zone system are 24 V AC. They connect through an RJ12-style 6-position connector, although the anywAiR zone control box uses only the four centre contacts for control.
Do not confuse the zone motor with a zone module. Some zone modules may be available in 24 V or 240 V versions. The information in this article relates specifically to the zone damper motor.
1. Zone motor electrical specification
| Item | Specification |
|---|---|
| Zone motor supply | 24 V AC |
| Frequency | 50 Hz on the referenced motors |
| Connector | RJ12 / 6-position modular connector |
| Control method | Open active / common neutral / close active |
| Control box capacity shown | 10 × RJ12 zone connections |
The referenced Advantage Air motor label shows a 24 V AC, 50 Hz input. The referenced AAD Red Zone motor is also marked AC 24 V, 50 Hz.
2. anywAiR zone control box RJ12 pinout
The control-box socket is a 6-position RJ12-style connection, but only the four centre positions are electrically used.
| Pin | Function | Used by control box? |
|---|---|---|
| 1 | N/A | No |
| 2 | Open Active | Yes |
| 3 | Common Neutral | Yes |
| 4 | Common Neutral | Yes |
| 5 | Closed Active | Yes |
| 6 | N/A | No |
Important: Only four control contacts are required. A 4-conductor modular lead may therefore be suitable where the connector and contact positions align correctly. If a 6-conductor RJ12 lead is installed, the outside positions (pins 1 and 6) are not used by the referenced control box.
3. Replacement motor and extension lead compatibility
| Supplier / motor | Harness pinout | Optional lead | Connector |
|---|---|---|---|
| National Air Parts (NAP) | Cross-pinned | 12 m | RJ12 |
| Australian Airconditioning Distributors (AAD) | Straight-pinned | 12 m | RJ12 |
| Metalflex | Straight-pinned | 12 m | RJ12 |
| Advantage Air | Straight-pinned | — | RJ12 |
Harness warning: A straight-pinned lead and a cross-pinned lead are not interchangeable. Confirm the motor supplier and cable type before connecting a replacement motor or extension lead.
Straight-pinned lead
| End A | End B |
|---|---|
| White | White |
| Black | Black |
| Red | Red |
| Green | Green |
| Yellow | Yellow |
| Blue | Blue |
National Air Parts 12 m cross-pinned lead
| RJ12 End A | RJ12 End B |
|---|---|
| White | Blue |
| Black | Yellow |
| Red | Green |
| Green | Red |
| Yellow | Black |

4. Motor-specific wiring references
Advantage Air / AAD motors
The supplied reference information shows these motors using a straight-through RJ12 harness. Wire colours remain the same from one end of the lead to the other.
Metalflex motor - standard harness
| RJ12 conductors | 3-core motor wire | Function |
|---|---|---|
| White + Black | White | Close Active |
| Red + Green | Blue | Common Neutral |
| Yellow + Blue | Black | Open Active |
For the optional 12 m Metalflex RJ12 extension harness, the reference shows a straight-through connection: blue-to-blue, yellow-to-yellow, green-to-green, red-to-red, black-to-black and white-to-white.
5. Technician checks
| 1 | Confirm the component being tested is the zone motor, not a separate zone module. |
| 2 | Confirm approximately 24 V AC is available from the zone control output when the motor is being commanded. |
| 3 | Identify whether the motor requires a straight-pinned or cross-pinned RJ12 harness. |
| 4 | Check that the centre four control contacts are present and that the plug is fully seated. |
| 5 | If the motor runs in the wrong direction or does not operate, verify the harness pinout before replacing the motor. |
Electrical safety: Isolate the system before altering wiring or changing a motor. Do not apply 240 V directly to a 24 V AC zone motor.
